The objective of this study was firstly, to develop an integrated theoretical model of a high performance organisational culture and secondly, to develop a measuring instrument based on the said model for assessing such a culture. The questionnaire was administered to a sampling frame of 600 employees of a manufacturing company that employs about 3 500 people. 313 Completed questionnaires (response rate 52%) were returned and used for the analyses. First level factor analyses were conducted on the item inter-correlation matrices of the 12 theoretical dimensions. A second level factor analysis on the sub-score inter-correlation matrix resulted in a single factor being extracted. Iterative item analyses yielded sound metric properties for each dimension and a Cronbach Alpha of 0,947 for the scale. The findings of further analyses are discussed.
